Application filed August 25, 1914.. Serial ltd-858,563.

To all whom it may concern:

Be it known thatl, NATHANIEL S. REEDER,

provide a door operating mechanism for railway cars by means of which the discharge doors of a carmay be moved to and held stationary in any desired position to permit the gradual and regulated discharge of the lad ing, as in ballasting; or if desired may be allowed to move to full open position without regulation, when a quick discharge of the lading is desired.

Another object of the invention is to provide a mechanism for regulating the speed of opening discharge doors which are operated by a non-regulated mechanism.

Another object of the invention is to provide means ,for connecting and disconnecting the mechanism for producing a regulated opening of the door and the mechanism for producing a non-regulated opening of the door.

A further object of the invention is to provide means for locking the regulating operating mechanism in and out of engagement with the non-regulating operating mechanism.

Referring now to the drawings, in which like reference characters refer to like parts, Figure 1 is a plan "iew of a portion of a car having one form of the door operating-mechanism applied thereto; Fig. 2 is a side elevational view of the same; Fig. 3 is an enlarged plan view of a portion of the car with the floor plates removed to more clearly show the invention; Fig. 4 is a sectional view taken on the line -l4 of Fig. 3 showing the regulating mechanism in engagement with the non-regulating mechanism; Fig. 5 is a like view showing the mechanisms out of engagement; Fig. 6 is a sectional view taken on the line GG of Fig. 3. Fig. 7 is an enlarged plan view of a portion of a car with a modified form of the invention applied thereto, the floor plates being removed to more clearly show the invention; Fig. 8 is a sectional view of the same taken on'the line 88 showing the regulating mechanism in engagement with the non-regulating mechanism; Fig. 9 isa like view showing the regu lating mechanism out of engagement with the non-regulating mechanism; Fig. 10 is a sectional view taken on the line 1010 of Fig. 8, and Fig. 11 is a sectional view taken on the line 11--11 of Fig. 7. Fig. 12 is an enlarged plan view of a portion of a car with a further modified form of the invention applied thereto, portions of the floor plate being removed to more clearly show the invention; Fig. 13 is a sectional view of the same taken on the line 13-13 and Fig. 14 is a sectional view taken on the line 14-44. of Fig. 12.

There are various types of cars to which the hereinafter described mechanisms may be applied, but as an illustration, a hopper car has been shown in the drawings, which comprises center sills 1, 1, side walls 2, end

sloping floor sheets 4, longitudinal ridges 5,

central sloping floorsheets 6, outside hopper sheets 7 and inside hopper sheets 8, all of which are secured together in a suitable manner.

9, 9 indicate two of the discharge doors which are located one on either side of the center sills 1, 1 and which at their upper edge portions are hinged to members 10 secured .near the lower edge portions of the sloping floor sheet 4. At their lower edge portions these doors are connected together by members 11, 11.

In the drawings a suitable quick or nonregulating door operating mechanism has been illustrated, having a crank 12 Opera tively connected with an operating shaft 13, which is suitably mounted near its outer end,

in a member 14 secured to the outside hopper sheet. The outer end portion of this shaft is madesquare so that a wrench may be applied thereto to rotate it, and is also provided with a ratchet wheel 15 with which a pawl 16 is adapted to engage. The crank 12 00111- prises spaced arms 17, 17 which are connected together by a web 18, and also comprises trunnions 19 and 20, which trunnions are journaled in the bracket members 21 secured to the center sills 1, 1.

22 indicates an actuating rod or link which is pivo-tally secured at one end to the members 11, 11 which are secured to the. discharge doors 9, 9, and which is pivotally connected at its other end to the arms 17, 17 of the crank 12. \Vhen the doors 9, 9 are in closed position the link or rod 22 rests on the web 13 of the crank 12. It will beseen-that Y to the center sill 1. Between the members. 24 and 25- the shaft 23 is provided with a worm 26 which may be keyed or otherwise secured thereto and which is adapted to be moved into and out of operative engagement with the teeth 27 of the worm wheel or quadrant 28 secured to the trunnion 20of the crank 12. The worm 26 is provided with an extension 30 which is preferably integral therewith and which is journaled in a link bearing member 31. This bearing member is pivotally connected with an arm 32 of a lever 33. The lever 33 besides having an arm 32, has also arms 34 and 35; the arm 34 being pivotally connected to the member 25, and the arm 35 being pivotally connected with one end of a rod or link 36. At its other end this rod or link 36 is provided with a lug 37 and is bent as at 38, and is pivotally connected with a crank arm 39 secured to an operating shaft 40. On the outer end portion of this shaft 40 a'leveror wrench 41' is provided by which the shaft may be rotated. It will be noted that the rod or link 36 passes over the operating shaft 39 and that the connection between the crank arm 38 and the rod or link 36 is beyond the center of suchshaft, thus locking the worm 26in engagement with the worm wheel or quadrant 28.

When it is desired to open the discharge doors of a car by the use of the preferred form of the regulating mechanism, as shown in Figs. 1, 2, 3,.4 and 6 of the drawings, the pawl 16 is first thrown out of engagement with the ratchet wheel.15. The hand wheel 41, secured to the operating shaft 23, is then rotated in the direction indicated by the arrow in Fig. 1 which causes the worm 26 to move the worm wheel or quadrant 28, crank 12 and actuating rod 22 in the direction indicated-by the arrow in Fig. 4. .It will be seen from the foregoing description that the operator has control of the operating echanism at all times and that the discharg doors maybe opened to any desired position and be held in such position. In the drawings alug 42 has been shown which is preferably integral with the worm wheel or quadrant 28. ,This lug is adapted to engage the end, of the worm 26 and limit the movement f of the "door. operating mechanism to produce a I maximum door opening of predetermined extent, and also to prevent the quadrant 28 from being turn :d so far in the direction of the arrow shown in Fig. 4, that it may lose its engagement with the worm 26.

When it is desired to open the discharge doors with the use of the regulating mechanism, the shaft 40 and the crank arm 39 are rotated in the direction, as indicated by the arrow in Figs. 4 and 5, by moving the lever or Wrench 41' to the position, as shown in dotted lines in the drawings, thus moving the rod or link 36 away from the shaft the above operation is'reversed.

In Figs. 7 to 11 inclusive a modification of the invention has been illustrated which differs from the preferred form of the invention only in the .mechanism for moving the worm 26 out of engagement with the worm wheel or quadrant 28 and the method of mounting the'shaft 23 on the center sill 1. In this modified form a shaft 42 has been provided which is journaled in members 43, 43 secured to the center sills 1, 1. To this shaft a lever 44 is secured, which lever is pivotally connected with the rod or link 36. A. member 45 is secured eccentrically to the shaft 42 and is adapted to slidably engage and move an eccentric strap 46. This strap comprises parts 47 and 48 which are secured together, around the member '45, by bolts 49. The part 48 of this strap, at its lower portion, is provided with spaced portions 50, 50 between which a block 51 is pivotally mounted, which block is adapted to receive the end portion of the shaft 23 and form a bearing therefor. The worm 26, in this form of the invention, is provided with an extension 52 which is adapted to be mounted in a slot in the bracket member 53 secured to the center sill 1, and engage such bearing member to prevent longitudinal movement of" the shaft when the doors are being operated. It will be seen from Fig. 8 of the drawings, that when the shaft'42 is rotated in the direction as indicated by the arrow, that the member 45 will before described in connection with the preferred-form of the invention.

1,202,31a I v m In Figs. 12 to 14 inclusive afurther modification of the invention has been illustrated in which the non-regulating door operating mechanism is the same as that hereinbefore described in connection with the preferred form of the invention. In this modified form of the invention, the lower end portion of the shaft 23 is suitably mounted in an arm 54 which is pivotally mounted on amember 55 secured to the center sill 1. The end portion 56 of this arm is movably mounted in a bracket member 57 secured to the center sill 1, and to hold the worm 26 in engagement with the worm wheel or quadrant 28, a bolt 58 or other equivalent means is passed through perforations in the flange 59 of the arm 54, and a perforation in the flange 60 of the bracket memberv57, and is held in position by a nut 61. When it is desired to disengage the worm 26 from the worm wheel or quadrant 28, the bolt 58 is removed and the arm 54 moved to the posi tion, as shown in dotted lines in Fig. 13 at which time the bolt 58 is again passed through the perforation in the flange 59 of the arm' 54 and through a perforation in the flange 60 of the bracket member 57, and is held in this position by the nut 61, thus locking the worm in a position'out of engagement with the worm wheel or quadrant 28.
